Found in the Engrish area of Reddit.
First sighting anywhere on the net!
Ðe original instructions are in ICELANDIC, and ðe English translation is dubious. Icelandic never appears on ðe web. Ðe letters shared wiþ Anglo-Saxon make it stand out immediately.
Later, I guess the rarity makes sense numerically. Iceland’s population is 400k, about the same as the Spokane metro area.
